Audio stream stalls
dj4mz:
Hi Jan,
unfortunately I have to come back to this topic.
Yesterday after the update I just tested with CW and not with phone. Today when trying to operate on the local UHF relais I recognized that TX audio is sometimes there and sometimes not! If TX audio goes away, then sometimes also RX audio is missing. It returnes after some while and stays available until I again try to transmitt. At that point TX may work or not ??? It very seldom happens, that even though PTT is pressed the TRX switches back to RX (of course with no RX audio). Looks very much like the SIP stream has been lost.
When this happens I can see RTP timeout time in the Remote RRC going down from 60 step by step until approx. 40 (or even less), then jumping back to 60 and everything works fine again for a few seconds.
Ping round trip time is 30...35ms.
Any hints?
More than ever: NEVER change a running system!

Edit: Looks like it does not really have to do with transmitting or not. Just have been monitoring the RTP timeout value in the Remote RRC. It is normally reading 60, and TX is possible. Suddenly the value starts to decrease and from that point on no TX audio is there. At some point, mostly at values arount 40, it jumps back to 60 and TX audio again is present. After some seconds the value again is decreasing and TX audio disappears.

When I made the upgrade I was in the shack and I was able to see the status of both units side-by-side using the web-based programming setup. What I noticed was the ports used for the audio were not the same. I couldn't figure out if that was something I set or that it was dynamic controlled by the firmware. Perhaps if you can watch the status of both units at the same time, you might get a clue as to what is happening.
For me, everything is working perfectly from the remote location so far. That will be the last time, I upgrade a perfectly working system. Hi.
Good luck, 73 Dick, WN3R

Which audio ports were different? If it were the "Out" ports then it's normal for them to be different from a session to another.

Hi Dick,
I haven't been at the remote shack when updating the device but as long as the settings available via the web interface are concerned, I couldn't find any differences. We already have had a discussion about changing ports in another thread. Also there, only the "out" ports have been changing, which is not a problem.
Jan, I have exported settings for both local and remote RRC. So if you are looking into this issue and the settings can be helpful, just let me know.
BTW: I'm back to V2.06. The downgrade caused even much more trouble but for now I looks like it is stabe again.

Life (as a software developer) would be a piece of cake if every bug was spotted and fixed immediately while working on new things. This issue you Simon(and a few others) have run into is what makes life less easy, but definitely more challenging ;)
I can understand that you went back to the "safety of old good" 2.06, though from our point of view it makes tracking down what happens harder as issues like this often need as much information as possible in order to be able the find the cause.
From the description of how it behaves it looks like the RTP(audio) stream simply "pauses" for X secs and then magically resume its operation. How often did it happen for you Simon? Were you able to start a session and just wait for a while and "voila" there it was? Or were there sessions which worked just fine?
